I installed BBM today via Google Chrome. The problem is that I can't find it anywhere on my phone now. I know it's installed because when I click the "Blackberry App World" icon and browse to "Blackberry Messenger", it says "installed".

I know that. I opened the blackberry website on my PC, using Google Chrome. I clicked on "Download BBM" and was told to plug the Blackberry into the computer, which I did. It downloaded the Application and said that it installed it successfully.
